[0002]

2. Description of the Related Art A ceiling-mounted lighting fixture of this type is used by attaching a fixture body to a ceiling surface, and is often used for a house having a low ceiling surface.

[0003] By the way, this type of general household lighting equipment is of a cord-hanging type in addition to the above-mentioned ceiling-mounted type, and it is usually easy to install and apply these equipment to indoor wiring. In addition, a hooking sealing body is provided on the ceiling surface. And in the case of a cord hanging type lighting fixture,
At the end of the power cord, a conductive hook is provided, and a hook sealing cap that is mechanically and electrically hooked and connected to the hook sealing body is attached. It is configured to:

On the other hand, in the case of a ceiling-mounted lighting fixture, the fixture body may be directly screwed to the ceiling surface, but since the weight of the fixture is heavy for some time, it is difficult to perform installation on a high ceiling surface. Usually, a simple mounting bracket is used. In other words, the ceiling-mounted lighting fixture exposes a hanging sealing body fixed to the ceiling surface from below the fixture body through an opening formed at a substantially central portion of the fixture body, and the upper surface side of the fixture body is placed on the ceiling surface. The fixture is directly attached to the ceiling surface, but when mounting the fixture body on the ceiling surface, first, a simple mounting bracket is attached to the ceiling surface around the hooking sealing body, and a screw is attached to this bracket. The mounting operation is performed by hooking the daruma hole provided in the instrument body with the attached mounting screw and temporarily holding it.

As described above, the ceiling-mounted lighting fixture eliminates the need to screw a heavy fixture body while supporting it on the ceiling surface by using the simple mounting bracket, which greatly facilitates installation work. there were. However,
Since ceilings are generally high and require scaffolding, even simple lightweight mounting brackets are difficult to screw onto the ceiling, making it incomparable to the installation of cord-mounted lighting fixtures. Met. Particularly, when the ceiling surface is a concrete surface or the like, it is difficult for a layman to perform the screwing operation itself, and there has been a demand for an improvement in the workability of attaching the ceiling-mounted lighting fixture to the ceiling surface.

[Problem to be solved by the present invention]
As shown in FIG. 4, on the lower surface of the hooking sealing body 1, a hooking sealing cap 4 having locking holes 3 formed on both side surfaces for supporting the instrument body 2 is attached. A ceiling-mounted lighting fixture 6 having a configuration in which a main body supporting member 5 that supports the fixture main body 2 is locked and supported in the locking hole 3 of the ring cap 4 has been proposed. (Refer to Japanese Utility Model Application Laid-Open No. 62-54414) This ceiling-directed lighting fixture 6 is configured so that the fixture main body 2 is supported by the hooking sealing cap 4 itself. This feature eliminates the need for screwing work and allows one-touch mounting. However, the hooking sealing cap 4 disclosed in Japanese Utility Model Application Laid-Open No. 62-54414 has a locking hole 3 for supporting the instrument body 2 formed on a side wall surface of the cap 4 itself. For many minutes, the hook sealing cap 4 itself is made of resin, and there is a risk that the hook sealing cap 4 may be damaged by the engaging operation of the main body support member 5, and there is a problem in durability and safety in long-time use. Further, the main body support member 5 has a fixed structure obtained by simply bending a sheet metal, so that mounting operation is difficult.
There has been a problem in appearance such as a flaw or the like occurring in the contact portion on the lower surface of the instrument body.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made in view of the above, and it is possible to obtain durability and safety, as well as easy mounting operation, and a ceiling-mounted lighting fixture which does not cause any damage on the lower surface of the fixture body. The purpose is to obtain a support structure for the main body.

[0008]

According to the present invention, a hooking sealing body fixed to a ceiling surface is exposed below an appliance body from an opening formed in a substantially central portion of the appliance body. An upper surface side is opposed to a ceiling surface, and a hooking sealing cap having locking holes for supporting the instrument body formed on both side surfaces is provided on a lower surface side of the exposed hooking sealing body. In a ceiling-mounted lighting device in which a main body supporting member is locked in the locking hole of the hooking sealing cap to support the fixture body, the hooking sealing cap is provided on an upper surface of the hooking sealing cap. A conductive hook which is mechanically and electrically hooked to and connected to the ring body; a cap body having a metal frame body mounted and supported on a peripheral surface of a side wall; Mounting holes on both sides of the A metal frame having a substantially U-shaped cross-section having a hole formed therein, wherein the main body support member is attached to the periphery of the opening on the lower surface of the instrument main body so as to be capable of moving forward and backward with respect to the locking hole. It is composed of stop claws. Further, the lower surface and the inner and outer surfaces of the metal frame are integrally covered with a resin cover.

[0009]

In the hooking sealing cap of the above construction, the cap body is made of resin, but the locking hole portion in which the locking claw of the main body support member is engaged and locked is a metal frame body, which is used for wear and tear. It is not damaged, is safe even when used for a long time, and has durability. In addition, since the main body supporting member has a movable structure capable of moving forward and backward, the mounting operation can be extremely easily performed. Also, there is no occurrence of appearance scratches or the like on the lower surface of the instrument body. Further, since the lower surface and the inner and outer surfaces of the metal frame are integrally covered with the resin cover, the metal frame is not directly exposed below the hooking sealing cap, and the aesthetic appearance is not impaired.
